Question

A car accelerates uniformly for 18khm to 36khm in 5sec. calculate​

Answer 1

Answer:

This might help you

Explanation:

V=36x5/18=10m/s

U=18x5/18=5m/s

t=5s

a=v-u/t

= 10-5/5

= 5/5

= 1m/s2

Answer 2

Explanation:

1.initial speed=u= 18km/hr=5m/s

or, final speed=v=36km/hr=10m/s

hence, accleration= (v-u)/t= (10-5)/5=1m/s×s

Therefore , Distance Travelled S=u×t +(1/2) a×t×t =5×5+(1/2)×1×5×5=37.5m
